Inline Ball Poppet Check Valves

FU-LOK® Inline Ball Poppet Check Valve stops reversed flow in order to protect instrumentations. When the differential pressure between inlet and outlet is higher than the cracking pressure, the ball will be pushed and open the passage. On the contrary, when the differential pressure between inlet and outlet is lower than the cracking pressure, the ball will be pushed back and close the passage to stop the back-flow.
